“Machete. A madman has a missile aimed at Washington. Go kick some ass.” That’s the set-up for Robert Rodriguez’ action movie sequel Machete Kills, and really that’s all it needs. Danny Trejo returns as the eponymous ex-Federale agent, Charlie Sheen plays the President of the United States and Michelle Rodriguez is back as the gun-toting, one-eyed Shé. There’s an explosive incident involving a helicopter, a speedboat gets used as a deadly weapon and Sofía Vergara fires bullets out of her boobs like the fembots in Austin Powers. Are you sold on this movie yet?

The trailers for Machete Kills so far have promised a movie that looks like everything Rodriguez fans will be looking for: a deliberately ludicrous plot, an undertone of self-aware humor and plenty of fun action sequences and creative kills that hark back to the director’s El Mariachi roots. A new TV spot has just been released that emphasizes Charlie Sheen’s appearances in particular, and also establishes Mel Gibson as Luther Voz, an eccentric arms dealer who is planning an even crazier plan than the attack on the White House.

Rodriguez himself is featured in one of three new promotional stills for Machete Kills, courtesy of The Playlist, along with Amber Heard, Sheen and the other Rodriguez. Heard, who seems to be in charge of “tech support” in the movie, is pictures in front of a gratuitous display of weaponry, while Sheen (who has possibly been featured in the marketing even more than Trejo has) sports a rifle of his own.

The cast also includes Jessica Alba, returning as U.S. Immigration and Customs Agent Sartana Rivera, Amber Heard as deadly beauty queen Miss San Antonio, Lady Gaga as Voz’s lackey La Chameleón, Alexa Vega as Killjoy and Demián Bichir as cartel leader Mendez the Madman. Gaga’s appearance in Machete Kills apparently impressed Rodriguez enough to give her a cameo in his upcoming sequel Sin City: A Dame to Kill For as well.

If there’s one concern about Machete Kills, it’s that there are so many cast members and characters that there may not be enough room for all of them to get decent screen time. All that Voz’s “army of assassins” really needs, however, is to each have one big and memorable introduction and fight scene with Machete – after all, this movie will probably be less about detailed and complex character arcs and more about making sure everyone enters with a bang and leaves with one as well.
